Gentoo Linux Security Advisory
Title: Ettercap: Format string vulnerability (GLSA 200506-07)
Severity: high
Exploitable: remote
Date: June 11, 2005
Bug(s): #94474
ID: 200506-07
Synopsis
A format string vulnerability in Ettercap could allow a remote attacker to execute arbitrary code.
Background
Ettercap is a suite of tools for content filtering, sniffing and man in the middle attacks on a LAN.
Affected Packages
Package: net-analyzer/ettercap
Vulnerable: < 0.7.3
Unaffected: >= 0.7.3
Architectures: All supported architectures
Description
The curses_msg function of Ettercap's Ncurses-based user interface insecurely implements formatted printing.
Impact
A remote attacker could craft a malicious network flow that would result in executing arbitrary code with the rights of the user running the Ettercap tool, which is often root.
Workaround
There is no known workaround at this time.
Resolution
All Ettercap users should upgrade to the latest available version: Code: | # emerge --sync
# emerge --ask --oneshot --verbose ">=net-analyzer/ettercap-0.7.3" |
